Good point - Clark's (tech page 17) cryptically mentions that "all 98 HP and higher require highest octane." That reminded me that My mom's few year old '67 110 automatic seemed to need Sunoco 260 (probably outrageously priced at over $0.30 / gallon) with anything approaching stock initial timing.  I never confirmed the vac advance curve, or  had the heads off to check for carbon build up or blocked cooling fins. I remember similar stories from 110 owners made me wonder about a description of the difference between 95/110 low comp and hi-comp heads being a cast hunk of metal protruding into the chamber.  I imagined it as a clumsy cooling fin, in reverse, potentially sucking heat into the head. A hot head raises the octane requirement a lot.
